+# CI/CD Integration for NEST (Issue #8)
+
+## Implementation Status: COMPLETE
+
+### What Was Implemented
+
+#### 1. GitHub Actions Workflow (`.github/workflows/ci.yml`)
+
+```
+Trigger: Push to main/master OR Pull Request to main/master
+
+┌─────────────────────────────────────────────────────────────┐
+│  1. LINT JOB (Python 3.11)                                  │

+```
+
+#### 2. Test Suite (`tests/`)
+
+**Files:**
+- `tests/__init__.py` - Package marker
+- `tests/conftest.py` - Shared pytest fixtures
+- `tests/test_agent_bridge.py` - 20 unit tests
+
+**Test Coverage:**
+
+| Test Class | Tests | What it validates |
+|------------|-------|-------------------|
+| `TestImportCheck` | 1 | Import verification |
+| `TestSimpleAgentBridgeInit` | 2 | Agent initialization |
+| `TestMessageRouting` | 3 | Regular messages, agent ID prefix, telemetry |
+| `TestSystemCommands` | 4 | /help, /ping, /status, unknown commands |
+| `TestAgentToAgentMessages` | 3 | @agent format, lookup, not found |
+| `TestMCPMessages` | 2 | #registry:server format validation |
+| `TestIncomingAgentMessages` | 2 | Incoming message parsing, loop prevention |
+| `TestResponseFormat` | 3 | Role, conversation ID, parent message ID |
+
+**Features:**
+- Each test includes detailed error diagnostics
+- `diagnose_error()` function provides:
+  - Error type and message
+  - Context (what was being tested)
+  - Potential causes based on error type
+  - Solutions
+  - Debug steps
+
+#### 3. Local Test Script (`scripts/local_test_windows_bash.sh`)
+
+```bash
+# Usage:
+./scripts/local_test_windows_bash.sh           # Run all (lint + tests)
+./scripts/local_test_windows_bash.sh lint      # Lint only
+./scripts/local_test_windows_bash.sh test      # Tests only
+./scripts/local_test_windows_bash.sh deps      # Check dependencies
+./scripts/local_test_windows_bash.sh install   # Install dev deps
+./scripts/local_test_windows_bash.sh help      # Show help
+```
+
+#### 4. Configuration Files
+
+- `pytest.ini` - Pytest configuration with test paths and markers
+- `.gitignore` - Updated to track `.github/` and `tests/`
+- `README.md` - Added CI status badge
+
+### Files Changed/Created
+
+| File | Status | Description |
+|------|--------|-------------|
+| `.github/workflows/ci.yml` | New | GitHub Actions workflow |
+| `tests/__init__.py` | New | Package marker |
+| `tests/conftest.py` | New | Shared fixtures |
+| `tests/test_agent_bridge.py` | New | 20 unit tests |
+| `pytest.ini` | New | Pytest config |
+| `scripts/local_test_windows_bash.sh` | New | Local test runner |
+| `.gitignore` | Modified | Allow .github/ and tests/ |
+| `README.md` | Modified | CI badge |
+
+### How to Use
+
+**Run locally before pushing:**
+```bash
+./scripts/local_test_windows_bash.sh
+```
+
+**Run specific tests:**
+```bash
+pytest tests/test_agent_bridge.py::TestSystemCommands -v
+```
+
+**What CI checks on every PR:**
+1. Lint - Catches syntax errors
+2. Tests - Validates agent_bridge.py functionality
+
+### CI Badge
+
+```markdown
+[![CI](https://github.com/projnanda/NEST/actions/workflows/ci.yml/badge.svg)](https://github.com/projnanda/NEST/actions/workflows/ci.yml)
+```
+
+### Future Enhancements
+
+- Add integration tests with mock MCP registry
+- Add test coverage reporting
+- Add multi-Python version testing if needed
